Golden Globe nominee Sam Smith and host Ricky Gervais were some of the first stars to arrive on the red carpet at the glamorous awards ceremony.

The singer, who is nominated for best original song for his single Writing's On The Wall from the James Bond film Spectre, opted for a classic black tuxedo, while Gervais added a pair of mirrored sunglasses.

Rodriguez, who opted for a navy blue Zac Posen gown, is nominated for the best TV comedy actress award for her title role in Jane The Virgin after winning for the same part last year and was joined on the red carpet by her father.

Alexander, who was dressed in a plunging emerald gown by Italian designer Genny, was accompanied by her fiancee Peter Facinelli.

Smith, who was dressed in a Dior tuxedo, arrived on the red carpet with Writing's On The Wall songwriter Jimmy Napes and admitted he was already feeling a little worse for wear.

He told NBC: "I'm actually hungover from last night, I started yesterday. I started like I mean to go on."

Asked if he would be acting up, he replied: "Hell yes! Me and Jimmy are drinking hard."

He added: "This is my first acting thing, I'm just freaking out. There are so many people here I recognise, it's great."

British actor Mark Rylance, who is nominated for both best supporting actor in a film for Bridge Of Spies and best actor in a limited series or TV movie for BBC drama Wolf Hall, added a brown hat to his dark suit.

He said: "It feels lovely to be celebrated. It's my first awards on the west coast. It's a way of encouraging people to see movies and that is a good thing."

Transparent actor Jeffrey Tambor, who is nominated for best TV actor in a comedy, was joined by his co-stars and the show's creator as he arrived at the ceremony.

He said having a food plan was the most important part of the night and whipped a cereal bar out of his pocket as he told NBC: "I have a pound of M&Ms in my left cheek, I'm not joking."

Michael Shannon, nominated for best supporting actor for his role as a real estate tycoon in 99 Homes, arrived on the red carpet in a Prada tux, saying: "This is very unlike where I'm from in Lexington, Kentucky but is maybe closest to the Kentucky Derby but there are no hats."
